9. S₂O ; 10. C₃N₄

Explanation:

Let's count the atoms, by the name

1. Chlorine Pentaflouride

1 Cl and 5F → ClF₅

2. Tellurium Hexafluoride

1 Te and 6F → TeF₆

3. Disulfur decafluoride

2 S and 10 F → S₂F₁₀

4. Tetraphophorus Decaoxide

4 P and 10 O → P₄O₁₀

5. Dibromine Monoxide

2 Br and 1 O →  Br₂O

6. Dihydrogen Disulfide

2 H and 2 S →  H₂S₂

7. Sulfur monoxide

1 S and 1 O → SO

8. nitrogen trioxide

1 N and 3 O → NO₃

9. oxygen monosulfide

1 O and 1 S₂ →  S₂O

10. tricarbon tetranitride

3 C and 4 N → C₃N₄

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

bcde is the incorrect answer it is a
